MAP04: 666 Feet Under (Claustrophobia 1024 2)

MAP04: 666 Feet Under is the fourth map of Claustrophobia 1024 2. It was designed by Chris Harriman (Impboy) and Walter Confalonieri (daimon), and uses the music track "Demons on the Prey," originally composed by Robert Prince for Doom.

Essentials
Take the chainsaw and use it to kill the imps in front of you, then open the south (left-hand) door to face more imps as well as one or two lost souls. Go down the staircase and open another door at the bottom to enter a narrow passage with more of the same monsters, then follow it until you reach a shotgun and an eye switch that will open some bars behind you. Kill some imps waiting behind the bars then climb up the steps to the blue skull key.

Drop down to the floor below, where a closet holding two imps and a demon has opened, then go back up the large staircase to find that bars are blocking your way back to the starting point. Kill the cacodemons that have appeared outside, then stand at the top of the stairs and look west through the fence to see a red pentagram switch next to a crucified marine, which you can shoot to open the bars. Go back to the starting point and open the west door, revealing four imps and a pain elemental on Hurt Me Plenty skill level or higher, then press another eye switch on the south wall to open the bars, revealing an imp/Hell knight standing on the exit teleporter.
